July 31--A truck became wedged under a railroad bridge in San Mateo on Wednesday night, halting Caltrain traffic and causing significant delays, officials said.
The truck got stuck about 7 p.m. as its roof came into contact with the underside of the Tilton Avenue bridge. By 7:45 p.m. the driver was able to extricate the vehicle and an inspector had arrived and deemed the overpass safe for trains at low speeds, said Christine Dunn, a Caltrain spokeswoman.
Trains resumed normal speeds about 8:05 p.m.
Dunn said that the bridge was one of four in San Mateo that was equipped with "crash bars," low-hanging obstacles positioned to warn drivers of the low clearance. She could not confirm whether the truck had struck the crash bars.
Southbound trains were stopped at Burlingame and Millbrae and northbound trains waited at San Mateo and Hillsdale while the scene was cleared. Though trains got moving quickly after the truck was removed, roughly 30-minute delays remained on the affected lines, Dunn said.
SamTrans, which serves all of the above stations, as well as BART, were both honoring Caltrain tickets. SamTrans also offered a shuttle between the Burlingame and San Mateo stations.
The Tilton Avenue bridge -- along with three others in San Mateo -- is slated to be replaced over the next few years because of its age and low vehicle clearance, Dunn said.
